No. 11/630,308filed on Apr. 21, 2008, which claims the benefit of the filing date ofU.S. Provisional Patent Application No. 60/591,883 filed Jul. 29, 2004,the disclosures of which are hereby incorporated herein by reference,and of French Patent Application No. 0406778 filed Jun. 22, 2004, thedisclosure of which is hereby incorporated herein by reference.

BACKGROUND OF THE INVENTION

The present invention relates to a control device for closing a luggagecompartment. More particularly, the invention relates to luggagecompartments that are available for passengers in an aircraft. However,the invention may also be applied to other types of passenger transportvehicles (e.g. trains, buses, boats).

It is customary to place luggage in luggage compartments that arearranged overhead. This solution avoids using just the floor for stowingluggage by utilizing space that generally goes unused.

In certain configurations, particularly in aircraft, the luggagecompartment comprises a mobile bin designed to receive luggage to bestowed. This bin may be moved between an open low position allowingaccess to the inside of the bin and a closed top position. The luggageis then placed in the bin when the latter is in a low position and thenis pushed upward towards its closing position. When closing the bin, onehas to push the bin and the entire load contained therein upward tobring it to a closed position.

Actuated luggage compartments may allow the luggage bins to be easilymoved from the open position to the closed position and to brake thisbin upon opening the luggage compartment. However, the control of suchluggage bins may not be natural to the user since it is totallydifferent from manual luggage compartments, whether assisted by a gascylinder or not. In some cases, this may be cumbersome for the user.Thus, for example, if the user has forgotten to place a piece of luggagein the luggage compartment and notices this during the closing of thecompartment, with a motorized compartment he may have to wait for thecompartment to close and then reopen the compartment so that he canplace the forgotten piece of luggage inside the compartment. With amanually controlled compartment, once the passenger notices that he hasforgotten to place a piece of luggage inside the compartment, hereleases the compartment which then opens immediately.

It is an object of the present invention to provide for an improvedcontrol device for a luggage compartment.

SUMMARY OF THE INVENTION

According to an exemplary embodiment of the present invention a controldevice for closing a luggage compartment is provided, the control devicecomprising a control mechanism, a mobile part and a detection unitadapted to detect a first event triggered by a user and to transmit afirst control signal to the control mechanism, wherein the first controlsignal corresponds to the first event, wherein the control mechanism isadapted to close the mobile part, and wherein closing of the luggagecompartment is triggered by the first control signal.

According to another exemplary embodiment of the present invention, thefirst event is one of a pressure signal applied to a zone and anapproach of a user. Furthermore, the mobile part comprises an openingfor loading luggage and a lower outside surface, wherein the zonecorresponds to the lower outside surface of the mobile part, and whereinthe detection unit is arranged at a level corresponding to the loweroutside surface of the mobile part.

According to an other exemplary embodiment of the present invention, thedetection unit is further adapted to detect a second event and totransmit a second control signal to the mechanism, wherein the secondcontrol signal corresponds to the second event applied to the zone,wherein the mechanism is further adapted to open the luggagecompartment, and wherein opening of the luggage compartment is triggeredby the second control signal.

It should be noted, that the first or second event may be a pressuresignal or a pull signal or, e.g., a sequence of single individualpressure signals.

The control device may send a control signal as pressure is exerted onthe detection unit. Once the pressure (equivalent to a force) stops, thesignal is modified and the mechanism for assisting the closing may takethis into account. Thus, the assist mechanism may be driven in such away that the luggage compartment, or more precisely its mobile part,reacts “naturally”: when no pressure is exerted on the mobile part ofthe luggage compartment, the mechanism assisting in the closing may bedisengaged. In this way, the luggage compartment may react in the sameway as when a user stops pushing on a “manual” luggage compartment andit opens again.

To have more ergonomic control means, the detection unit advantageouslyextends longitudinally with relation to the opening of the mobile parton a length corresponding to at least half of the width of the luggagecompartment and is found near the opening of the mobile part of thelatter. The detection means are then found on the mobile part at thelocation where a user naturally attempts to push the luggage compartmentclosed.

The detection unit comprises, for example, a pressure sensor chosen fromamong a set of resistive sensors and capacitive sensors.

According to an exemplary embodiment, the detection unit is for exampledisposed at the bottom of a groove, and a rest bar is elasticallymounted in the groove in such a way that it acts on the detection meanswhen pressure is exerted on it. The rest bar is presented for example inthe form of a roughly rectangular section shaped piece with an interiorsurface designed to act on the detection means, an exterior surfaceopposite from the interior surface on which a user may exert pressureand two lateral surfaces, the lateral surfaces each having a flangeextending longitudinally, and the sides of the groove receiving the restbar each present a housing in which a flange of the rest bar ispositioned.

In this exemplary embodiment, a printed circuit is for example housed atthe bottom of the groove, and the interior surface of the rest bar isconductive, the conductive surface being at a distance from the printedcircuit when no pressure is exerted on the rest bar.

In another exemplary embodiment of the present invention, the detectionmeans cover for example the major part of the lower exterior surface ofthe mobile part. Then they are present in the form of a film. Thislatter is, in a variation of the embodiment, electrically insulated fromthe lower exterior surface of the mobile part by a layer of insulatingmaterial and is covered by a decorative layer.

The present invention also relates to a luggage compartment designed tobe placed overhead, this compartment comprising a mobile part between anopen position and a closed position and a mechanism for acting on saidmobile part to promote its closing, characterized in that the inventioncomprises a control device such as described above to act on saidmechanism.

According to another exemplary embodiment of the present invention, adetection unit for integration in a luggage compartment of an airplaneis provided, the detection unit comprising a capacitive sensor with anactive layer, wherein the capacitive sensor is adapted to detect anevent triggered by a user. The detection unit is adapted to transmit afirst control signal to a control mechanism, wherein the first controlsignal corresponds to the first event.

According to this exemplary embodiment of the present invention, thecapacitive sensor may be completely integrated into the luggagecompartment hatrack. If the capacitive sensor now detects an event whichis triggered by a user, such as, for example, a particular usermovement, a corresponding control signal is transmitted to the controlmechanism. According to an aspect of the present invention, the controlmechanism may then help the user to open or to close the luggagecompartment.

According to another exemplary embodiment of the present invention, thedetection unit further comprises a circuit adapted for providing avoltage to the capacitive sensor and for analyzing an electric fieldgenerated by the capacitive sensor, wherein the electric fieldcorresponds to the event triggered by the user. Therefore, the circuitmay be adapted for determining whether a corresponding user activity orevent has occurred. For example, the circuit may be calibrated or evenprogrammed such that a specific event can be clearly identified as, forexample, a user's intention to close the luggage compartment. On theother hand, the circuit may be further calibrated or programmed todetect and identify a second event corresponding to the user's intentionto open the luggage compartment. It should be noted, that thesensitivity of the capacitive sensor in combination with the circuit maybe tuned individually according to individual requirements for itsapplication.

According to another exemplary embodiment of the present invention, theevent is one of a pressure signal applied to a zone and an approach of auser.

Therefore, the sensor may detect pressure applied to a certain area ofthe luggage compartment by detecting a change in capacitance.Furthermore, the circuit may be calibrated such that not only a pressuresignal may be detected, but even an approach of, for example, a user'shand to the zone of the luggage compartment, resulting in the change ofcapacitance.

According to another exemplary embodiment of the present invention, theactive layer is a conductive material, which is electrically isolatedfrom a surrounding compartment structure.

Furthermore, the active layer may comprise carbon fibre, aluminium orcopper foil or a copper or aluminium web or grid material.

The use of carbon fibre as active layer may result in an easy and costefficient integration of the detection unit into the luggagecompartment.

According to another exemplary embodiment of the present invention, theuse of a detection unit for a control device for closing a luggagecompartment in an airplane is provided.

These and other aspects of the present invention will become readilyapparent from and elucidated with reference to the embodiments describedhereinafter.

Exemplary embodiments of the present invention will be described in thefollowing, with reference to the following drawings:

DETAILED DESCRIPTION

FIG. 1 represents a luggage compartment designed to be placed overheadin an aircraft (or in another passenger transport vehicle).Conventionally, this luggage compartment comprises a fixed box 2 and amobile part 4 between a closed position in which it is completely insidethe fixed box 2 and an open position in which it is projected out ofthis box 2.

One may suppose for example that the mobile part 4 passes from its openposition to the closed position by pivoting around an axis 6 that isroughly horizontal. Other movements are of course possible. A mechanismthat is not shown provides assistance first during the opening of theluggage compartment and secondly during its closing.

During the opening of the luggage compartment, particularly when thelatter is loaded, one has to prevent the mobile part 4 from fallingsuddenly. In fact, this may create impacts that in time damage theluggage compartment and may also cause the luggage inside thecompartment to fall. During closing of the luggage compartment, theassist mechanism provides a force that is opposed to the weight of themobile part 4 and the luggage that it contains. In fact, to pass fromthe open position to the closed position, the mobile part 4 passes froma low position to a high position and thus the force of gravity isopposed to this movement.

The assist mechanism is, according to an exemplary embodiment, a motorthat is used either to brake the lowering of the mobile part 4 or todrive the mobile part in a raising movement. This mechanism may also bea passive mechanism comprising one or more assist cylinders.

The following description particularly relates to the control means foracting on the assist mechanism equipping the luggage compartment duringthe closing of this compartment.

In FIG. 1, a linear control zone 8 is disposed on both sides of a handle10. The latter is conventionally used for releasing the mobile part 4with relation to the fixed box 2 and for thus controlling the opening ofthe luggage compartment.

The mobile part 4 is presented in the form of a bin in which luggage maybe introduced. This bin slides (or pivots) with relation to the fixedbox 2. This bin comprises a bottom wall that forms the lower surface 12of the mobile part 4, and also the luggage compartment. The mobile part4 also presents an opening 14 for allowing the introduction andretrieval of luggage to be stowed. In the closed position of the luggagecompartment, the opening 14 is entirely retracted within the fixed box2. In the open position of the luggage compartment, the passenger hasaccess to the opening 14 for introducing or retrieving his luggage intoor from said compartment. FIG. 1 represents the luggage compartment in ahalf open position. One also notices in FIGS. 1 and 2 the presence of anedge 16. The latter is disposed at the bottom of opening 14 forobstructing the fall of objects out of the luggage compartment when thelatter is particularly in an open position. This edge 16 extends alongthe lower surface 12 of the mobile part. The handle 10 is conventionallycentered with relation to the mobile part 4 of the luggage compartmentnear the edge 16 and the opening 14.

In an exemplary embodiment represented in particular in FIGS. 2 to 4,the control means of the mechanism are disposed at the linear zones 8found on both sides of the handle 10. These linear zones 8 extendroughly parallel to edge 16.

The control means comprise a printed circuit 18, a conductive element 20and a rest bar 22.

FIG. 3 schematically shows these elements. The conductive element 20 isfixed on the rest bar 22, for example by bonding, and faces the printedcircuit 18. In a position of rest, when no pressure is exerted on therest bar 22, the conductive element 20 is at a distance from the printedcircuit 18. There is no contact between these two elements. On the otherhand, when pressure is exerted on the rest bar 22, in the direction ofthe printed circuit 18, the conductive element 20 is driven by the restbar 22 and comes into contact with the printed circuit 18. This contactis then detected by electronic means that are not represented and anelectric signal is sent to the assist mechanism.

The conductive element 20 is presented for example in the form of arectangular band whose dimensions roughly correspond to those of theprinted circuit 18, which is also rectangular. The element is forexample made of carbon or a carbon base. Other conductive materials mayalso be possible here for making this conductive element 20.

The printed circuit 18 is represented in a top view in FIG. 4. Onenotices that this printed circuit 18 comprises a track 24 in the shapeof squared notches extending over the entire length of the printedcircuit 18. As can be seen in FIG. 2, the printed circuit 18 ispositioned at the bottom of a groove 26 achieved in the lower surface 12of the mobile part 4. This groove 26 is achieved in the exterior side ofthe lower surface 12. The rest bar 22 closes the groove 26 and slightlyprojects outside of the groove.

To maintain the conductive element 20 at a distance from the printedcircuit 18 in a position of rest, the rest bar 22 presents lateralflanges 28. These flanges are positioned in the corresponding housingsprovided in the lateral sides of the corresponding groove 26.

The rest bar 22 is a shaped piece, made from an insulating material, forexample a synthetic material, and presents an interior surface thatcarries the conductive element 20, an exterior surface that projects outof the groove 26 and two longitudinal lateral surfaces. The flanges 22are carried by the longitudinal lateral surfaces and extend roughlyperpendicularly to the latter. The lateral flanges 28 are positioned onthe rest bar 22 and the corresponding housings are achieved in the sidesof the groove 26 in such a way that when the lateral flanges 28 are inplace in their housings, the conductive element 20 is maintained at adistance (on the order of mm or tenths of mm) from the printed circuit18.

As shown in FIG. 2, the groove 26 may be achieved in a piece 30 that ispositioned on the free extremity of the lower surface 12 of the mobilepart 4. This piece 30 may fit into this free extremity, on the side ofthe opening 14, or may be molded over. The piece may also integrate forexample the edge 16 described previously.

The action on the control means described above may be done verynaturally. When a passenger has placed his luggage in the luggagecompartment (in an open position) he pushes on the lower surface 12 ofthe mobile part to close the luggage compartment. Furthermore, henaturally pushes on the side opposite to the pivot axis 6 of the mobilepart 4, even more so as this zone of the lower surface 12 is the zonethat is normally the closest and most accessible to him. Thus, bynaturally pushing on the mobile part 4 of the luggage compartment toclose the compartment, the passenger (or the personnel on board or anyother person) acts on the control means of the assist mechanism. Anelectric signal is then sent by the control means. An electronic box(not represented) receives this signal and consequently controls theassist mechanism. Once the passenger (or other person) stops pressing onthe rest bar 22, the electric signal emitted by the means describedabove is interrupted. The electronic box may take this information intoaccount. This modification in the signal may be interpreted as the willof the user to stop the closing movement of the luggage compartment. Themechanism may then react in various ways. It may for example release themobile part 4 in the position in which it is found when the contact onthe rest bar 22 has stopped. It may also provide at this time thereopening of the luggage compartment. In some conditions, a closing mayalso possibly be considered (for example at the end of the contact whenthe luggage compartment is practically closed).

In another embodiment, the capacitive sensor 34 of the detection unitentirely covers the lower surface 12 as shown in FIG. 5, which is asectional view of the lower surface 12 of the mobile part 4.

In the embodiment shown in the drawing, this lower surface 12 isconstructed of carbon. The surface comprises several layers 32 in acarbon fiber based composite material. The exterior side of the lowersurface 12 is covered by the capacitive pressure sensor 34 presented inthe form of a sheet. the sensor 34 is electrically coupled to a circuit500 adapted for providing a voltage to the capacitive sensor and foranalyzing an electric field generated by the capacitive sensor, whereinthe electric field corresponds to the event.

As the lower surface 12 of the mobile part 4 is constructed of aconductive material (e.g. carbon or any other conductive material, e.g.copper), it has to be insulated electrically from the capacitive sensor34 of this lower surface 12. Also, the conductive material may be afoil, layer or grid made of a metal such as aluminium or copper. Thisisolation may be achieved by placing a fibreglass based insulating film36 between the lower surface 12 and the capacitive sensor 34.Furthermore, e.g. for reasons of protection or for aesthetic reasons,the capacitive sensor 34 is covered by a decorative film 38. This film38 may present various appearances. For example, it may be made of afabric that matches the seats of the vehicle in which the luggagecompartment is located, a synthetic material, etc.

FIG. 6 shows a plan view of the mobile part of a luggage compartmentcomprising a capacitive sensor 34, which is integrated into the mobilepart 4. According to this exemplary embodiment of the present invention,the capacitive sensor 34 may cover a considerable fraction of theexterior side of the lower surface, e.g. an area of 114 cm×16 cm. Thecircuit 500 may, e.g., be arranged behind the handle 10.

However, the capacitive sensor 34 may even cover the entire exteriorside of the lower surface 12 (except at the handle 10).

As soon as a user touches the lower surface 12 of the exterior side oras soon as the user approaches the capacitive sensor 34, this event isdetected and a corresponding electric signal is sent to an electronicbox 500 utilized for managing the control mechanism which assists formoving the mobile part 4. Here, an operation may be provided that issimilar to the operation described with respect to the first embodimentof the control device. This may allow for example for a closing of theluggage compartment by applying a minimum force. Therefore, the user maybe able to close the luggage compartment with his fingertips alone.

It should be noted, that the moving speed with which the controlmechanism moves the mobile part may depend on the amount of pressureapplied be the user. For example, small pressure may result in a smallclosing speed an a big pressure may result in a high closing speed ofthe luggage compartment.

However, the detection unit, which comprises the capacitive sensor 34,may further be adapted to detect a second event, corresponding to theuser's intention to open the luggage compartment. This event may, forexample, be a certain sequence of single pressure strokes or a sequenceof approaches of the user's hand. For example, one short stroke maytrigger the closing of the luggage compartment and two short strokes maytrigger the opening of the luggage compartment. Therefore, thecapacitive sensor 34 may comprise an active layer integrated into thebin-material of the luggage compartment. The active layer may comprise aconductive material, e.g. copper or carbon fibre, and may beelectrically isolated with respect to the compartment structure.

According to an exemplary embodiment of the present invention, a carbonfibre material may be used as active layer, since carbon fibre may beused as a building material of other parts of the luggage compartment aswell.

Using carbon fibre as active material layer may result in a homogeneousmaterial composition of the luggage compartment structure, such that thesensor is not visible from the outside. Therefore, such sensors may beintegrated into a cabin structure of the airplane without being visible.Thus, the cabin design may not be negatively influenced by the sensorintegration.

The detection unit may further comprise a circuit 500 adapted forproviding a voltage to the capacitive sensor 34 and for analyzing anelectrical field generated by the capacitive sensor 34. The circuit 500may be adapted in form of an integrated circuit or any other circuitadapted for supplying the capacitive sensor 34 with electricity andanalyzing respective detection signals.

The active layer may be electrically coupled to the circuit box 500. Useof the detection unit comprising a capacitive sensor described above mayprovide for an intelligent switch which can easily be integrated intothe cabin structure during its fabrication process. By isolating thesensor from its surrounding structure, e.g. by using glass fiber matssurrounding the sensor, the power required for generating the electricfield may be reduced to a minimum. Thus, the electromagneticcompatibility may be further improved.

During fabrication of the active sensor layer 34, the active sensorlayer 34 is embedded between one or a plurality of glass fibre mats, inorder to electrically isolate the active layer 34 from the surroundingstructure. According to an aspect of the present invention, the sensorlayer 34 is the first layer after the isolating layer. However, thesequence of isolating layers and active layers may be varied accordingto electronic or sensitivity considerations. For example, if it isdesirable to have a sensor layer on each surface of the mobile part(i.e. the inner surface and the outer surface), two sensor layers may beimplemented, electrically isolated by a glass fibre mat, resulting in asandwich of two active layers with a glass fibre mat in between.

During the production procedure of the compartment structure, thedifferent layers are laminated by applying a high pressure and heat.After lamination and hardening, the resulting compartment, whichcomprises the sensor, may be further processed. This further processingmay comprise varnishing or further lamination steps.

The capacitive sensor may be used as an invisible switch integrated intothe cabin structure, in particular as special designed light switches intoilets or other passenger areas. Furthermore, the sensor may be used asan invisible switch for opening compartments, which are only used by thecabin crew. Furthermore, the sensor may be used as a switch forcontrolling the cockpit door locking system.

It should be noted, that the sensor may also be used in areas which aresubject to extreme physical conditions, such as heat or moisture.

The embodiments of the control means described above may allow forhaving a motorized luggage compartment that is operated in the samemanner as a manual luggage compartment. The user may thus very naturallyuse this luggage compartment, possibly without even noticing that thiscompartment is motorized. The means described above may even be used tomeasure the force exerted by the user of the luggage compartment. Thus,the assist mechanism, when it is motorized, may be driven according tothe force exerted by the user on the mobile part of the luggagecompartment.

FIG. 7 shows a luggage compartment according to an exemplary embodimentof the present invention, comprising a sensor layer 34 and an electronicbox 500 adapted for providing a voltage to the capacitive sensor and foranalyzing an electric field generated by the capacitive sensor, whereinthe electric field corresponds to the event.

It should be noted, that the present invention is not limited to theembodiments described above by way of non-limiting examples. Theinvention may also relate to all variations of embodiment that arewithin reach of a person skilled in the art of the following claims.

The sensors described are given by way of non-limiting examples. Here itmatters that these sensors are distinguished from an “on/off” typebutton. The signal emitted by these sensors indicates if the user exertsa force on the mobile part of the luggage compartment or not.

The description was made with relation to a luggage compartment whosemobile part is a pivoting part. Of course, the invention may also beapplied to luggage compartments presenting different kinematics.

The form and size of the sensors may be different from the form proposedand may be adapted to the respective application in aircrafts, cars,buses, trains or furniture. Also, such sensor may be applied as hiddenswitch or design switch e.g. in laptops or other electrical devices. Thefirst embodiment proposes two sensors located on both sides of thehandle of the luggage compartment. It is possible to provide a largernumber of sensors. In a second embodiment, the entire exterior surfaceof the luggage compartment is covered by a sensor. An intermediatesolution with a sensor covering for example half or a third of the lowersurface of the luggage compartment may of course also be possible.

It should be noted, that, according to an aspect of the presentinvention, the assist mechanism or control mechanism may be adapted asan electrical motor, as a pneumatic or hydraulic mechanism or as a gascylinder.

It should be noted, that the term “comprising” does not exclude otherelements or steps and the “a” or “an” does not exclude a plurality andthat a single processor or system may fulfil the functions of severalmeans recited in the claims.
